Mecolpress, 50 years in the hot forging sector
This year Mecolpress has reached the goal of its first half century of activity by presenting a new continuous and discontinuous cycle press at EMO exhibition in Hannover, held last September.
In the present of Mecolpress there is also an investment in the world of electric scooters.
The video story by the management of Mecolpress:
Established in 1969 by Giulio Molinari, Giulio Barbisoni and Pietro Caggioli, MECOLPRESS was founded as a manufacturing company of mechanical presses for brass components hot forging. A few years later, in 1973, the company acquired its current production site in Flero, in via Don Maestrini, initially extended over an area of 2,000 square meters, and then it expanded increasingly reaching 6,000 square meters in 1993. Today Mecolpress has acquired a second industrial area next to the first one where the construction of a warehouse is coming to an end, reaching a total area of 30,000 square meters.
In addition to the industrial area expansion, over the years Mecolpress has aimed higher and higher thanks to the acquisition of two important brands of the screw presses production: the Italian company, Dellavia (1993) and the Swiss company, Osterwalder (1998). The company has always distinguished itself as an avant-garde reality in the forging sector: remarkable are the production of the first continuous cycle mechanical press in 1983, the production of the first continuous cycle electronic press in 1993, the design and construction of the hydraulic press for hot forging of brass components without flash in 2008 and the presentation on the market of the screw press with direct drive motor in 2013.
In September of this year, in occasion of EMO exhibition in Hannover, Mecolpress officially presented the new series of continuous and discontinuous cycle eccentric presses, the HEAVY series.
This new machine has an innovative and modern structure, more robust, and designed to simplify the control and maintenance for the operator. The automation and the dies lubrication of the machine was completely renewed, thanks to the addition of a bearing, that allows, among other things, for vibrations reducing and it is provided with a new intelligent software for the production process analysis and for predictive maintenance.
On 31st August, Mecolpress celebrated its first 50 years of activity by opening its doors to the families of the employees who work at the Flero site every day. In this first half century of activity, there have also been moments of sacrifices and difficulties, but the tenacity and determination of its founders allowed Mecolpress to emerge very quickly in a particular market such as the forging one.
The second generation played an important role in the history of the Rhinoceros, as well, in particular, during the economic crisis of 2008, when the company could make courageous decisions, expanding its business, pushing on the accelerator of innovation and research, trying to renew itself and pushing beyond the borders drawn by parents. Now the company has reached the maturity of an important reality that operates all over the world, where the glorious history of its beginnings coexists with the desire to get involved that has especially characterized with research and innovation the last years.
With the background generated by this mix of values, now also the third generation appears in the management panorama.

Mecolpress, a new adventure
In 2018 Mecolpress acquired the majority of the shares of ME Group, manufacturing company of electric scooters with an unique design, becoming the reference partner alongside the founders. The entry of Mecolpress formally coincided with the passage of ME Group from Innovative Start Up to Innovative SME. This formal transition was in fact also substantial, thanks to the contribution of Mecolpress from a financial point of view and above all from the point of view of know-how and industrial approach to the organisation of the company. ME is the first scooter in the world with a patented frame made of SMC (Sheet Moulding Compound), a compound of thermosetting resins with excellent performances in terms of strength and resistance in relation to its weight. This electric scooter can be recharged like a mobile phone: it can be fully recharged in 3-6 hours (depending on the battery charger used), connecting the scooter directly to a domestic outlet in the garage or office or extracting the battery.
The ME Start Edition version (sold out) was followed by the range available from the 2019 season: 2.5 kW moped model, 45 km/h top speed (limited by law) and 80 km range and 6 kW model with a speed of 80 km/h. Touch display, USB socket and a range of accessories in continuous evolution complete the equipment of ME.
Company numbers:
Mecolpress has grown over the years both in terms of volume of the industrial area and in terms of numbers. Starting from the employment situation: in 1985 Mecolpress had 29 employees, in 2018 it practically doubled its staff to 55 employees. Turnover and production are also growing: in 1985 the company turnover was just over 2.7 million euros. By 1995, turnover rose to 7.5 million euros and then the last available turnover (2018) exceeded 11.3 million euros.
Over the years production has also gone hand in hand with turnover increase. Today Mecolpress has 559 customers in 59 countries worldwide. All over the world there are 1126 Mecolpress machines, including screw presses (101), mechanical presses (806), hydraulic presses (40) and trimming machines (179). Most of them (763) are located in Europe, but the Flero-based company has also exported in Africa (62), Americas (103) and Asia (198).
In addition, Mecolpress is particularly active in after-sales service. The heart and pride of Mecolpress is its large spare parts warehouse, which is able to supply accessories or spare parts for machines produced fifty years ago. For this reason, in addition to the sale of machinery, there is a wide activity related to the service and supply of accessories (such as tools, arms, spare parts, etc..) in the order of more than 1,000 units, bringing the total production of machinery and spare parts to 2183 pieces.
Screw presses
Come to discover the application sectors and the functioning of Mecolpress screw presses. Used for hot forging, these presses can be employed with every type of material and are distinguished by the realization of full parts.
Screw presses functioning
Mecolpress offers a wide range of presses both hydraulic and mechanical. Also screw presses fall into this last category, ideal for hot forging of parts of great dimensions or that require more passages for shaping. These mechanical screw presses can be provided with a disc friction control or a direct control with electric servomotor.
The screw press choice is determined according to the type of part you want to forge. Hallmark of the screw press is its ratio force-machine dimension, that results greater than the specific one of an eccentric mechanical press.
These mechanical presses can be used with every type of material and the frequency of strokes is quite reduced. For this reason, there is a tendency to use this machine for the production of little batches, that is often true for parts of great dimensions.
Mecolpress offers to its customers three lines of screw presses: Dellavia series and Osterwalder series that are friction screw presses, and TDS series with electric motor. All the screw presses models can be integrated with complete and automatic forging lines, that from bar raw material realize finished forged parts.
The tonnage can go from 170 tons up to more than 2.700 tons, to be chosen according to the geometrical shape you want to obtain and of course to the material to be forged.
The applications
The screw presses are used for the realization of parts destined to different application fields including for example, watch cases, parts for sport equipment, for automotive or for biomedical titanium prothesis.
So, it is possible to produce very small parts, such as for example, clothing zipper pullers till to aluminum sport bows of 1 m of length. The parts, produced by this type of machine, are not cored but full.
The screw presses are very used also in the fashion field to realize belt and bag buckles, with brand-specific shape.
In order to understand which model is more suitable to your production needs, all you have to do is to address to Mecolpress sales department. Thanks to the experience gained with years of activity in the hot forging field, we can suggest the most performing machine according to the type of part you want to forge, and it is possible to carry out a test directly at our premises.
Why to choose Mecolpress presses?
Mecolpress makes available to its customers quality presses and all its technologic know how. For those who need high performing machineries for hot forging we are a reliable and with a solid experience partner in this field, gained in many years of activity.
Whether it is an entire forging line or a single machinery, Mecolpress can suggest the most performing solution for production and offer a technical support able to face every need.
A first meeting to understand the necessities
When a new potential customer contacts us expressing its need to buy a press, our sales department organizes immediately a first meeting either at customer’s or at our premises in order to show the different machines and their functioning.
During this phase, to us it is of fundamental importance to understand the types of the parts to be forged and which could be the eventual criticalities connected to the single parts in order to be able to propose the most suitable press. In many cases our offers are based directly on the drawings of the parts to be forged that are analyzed by our technical office in great details.
In order to understand which is the best press, our technical office takes advantage of a software that can simulate on the computer the action of the machine. In this way we provide a valid tool for the identification of the machinery that meets the productive needs.
Some customers in addition to the single press require the entire hot forging line and, in this case as well, we can provide all the necessary machineries, and to optimize the production.
Forging tests at Mecolpress
Once the most fitting press for the customer has been identified, even if this is hydraulic or mechanical, we carry out forging tests at our premises. So, the customer can be sure in advance of the final result before starting the production at his premises.
In order to carry out the test, the dies for the realization of the wished parts are mounted on the machine. In case the customer does not have the die, there is the possibility to commission it directly to Mecolpress. Indeed, our company offers a complete service to support the customer during all the productive steps and can also offer this component.
During the many years of activity we have gained high technical skills and we have confronted with different situations. The gained experience has turned us into a partner that can understand the forgers needs, able to propose mechanical or hydraulic press for a specific production type.
Friction or electrical screw press?
There are electrical or friction screw presses. Which to choose? The choice of the model is linked to the type of parts you want to forge, but also to the press performance. Discover the differences between these types of screw press by reading this article.
The mechanic friction machine is provided with a flywheel that rotates the screws clockwise or counterclockwise so that to let the slide go down or go up. In this case the transmission of the motion from the electric motor to the flywheel happens through the friction created on a leather belt. This model does not permit a direct control of the motor and of the flywheel, even if it presents considerable advantages in terms of energy saving. Indeed, a friction screw press has a medium consumption of about 40 KWh.
These presses require a smaller investment than the one of the screw presses with electrical servomotor, but they need the leather belt replacement, necessary for the slide movement when it wears.
Suitable for the hot forging of every type of material, the friction screw presses are used for the production of full parts.
This press, as opposed to the friction one differs for an electrical motor directly mounted on the flywheel, in the upper side of the machine, that rotates the screw. Thanks to this characteristic, the electrical screw press allows a better control of the productive process. Indeed, it is possible to check the descent and rise speed at any moment, to have direct feedback about the production of the machine and to calculate the necessary tonnage for the hot forging of parts you want to produce.
The electrical screw press requires more electrical energy, but its components wear less, and it is particularly indicated for the production of parts that require more strokes to be completed. In addition, it is possible to obtain much more energy with a reduced stroke, which does not always happen in the case of friction screw press. As a result, this machine has a rate of production slightly higher than a traditional machine.
The mechanical screw presses of Mecolpress TDS series are moreover provided with Calipso software, which is also developed by our company, that allows the data collection and recording in real time. In this way the end-user can do a process evaluation and intervene to optimize it.
Mecolpress proposes to its customers both friction screw presses and direct control with electrical servomotor control screw presses, developed to satisfy the different productive needs and suitable for the forging of full parts destined to sectors such as automotive, medical and sport one.
Training courses for hot forging
Starting from an inner necessity, Mecolpress has extended the training courses specific for hot forging machineries as a high-quality service against payment that can be offered to its customer companies.
Thanks to the course, it is possible to optimize the production and to improve machines maintenance.
The training value according to Mecolpress
Training is very important, especially in an even more complex productive context and in an even more competitive market. That’s why Mecolpress has felt the need to avail itself of the experience of a hot forging specialist to organize an inner training course of high level.
Understanding the world our customers operate in and learning the art of forging in the best way has always been our priority: therefore, we addressed to Riccardo Segreto that in this interview shared with us very useful suggestions and advanced technical information.
Una volta conclusa questa esperienza molto positiva all’interno della nostra azienda abbiamo quindi deciso di offrire questo servizio di alta formazione anche ai nostri clienti.
Advantages of training courses against payment
Training courses represents a very important instrument for the companies that deal with hot forging, because they offer to people who operate with mechanical and hydraulic presses very concrete and deepened indications regarding how to use them in the best way and to optimize the production.
Today it is not easy to find forging specialists that are available to teach trade secrets. Riccardo Segreto is an independent and very skilled figure, available to share with the companies useful suggestions in order not to wear the press or the die and to improve therefore the productive capacity.
Therefore, a highly qualified staff will be able to carry out some maintenance operations in complete autonomy on machineries for hot forging without the need of Mecolpress customer care service against payment. A correct use of the machine brings therefore to lesser damages and a reduction of machine stops that have a big effect on the production and then on the costs to support.
Our training courses against payment are custom-made developed according to customer’s needs and aimed to the types of presses present in the factory of the company that asked for training. Moreover, they provide an in-depth analysis of the parts to be forged and indications on how to forge them in the best way.
Thanks to our specialist, for example, it is possible to learn how to carry out in the best way the die lubrication and therefore how to prevent its wear and how to adjust the machine stroke. Working correctly with the press has as a result a considerable decrease of costs for our customer companies and that’s why we are firmly convinced that our training courses can represent an added value.
According to companies necessities, the courses can be held at our or customer premises and these have a duration of one or two days, according to the specific program.
Should you need further information regarding training courses, you just have to contact our sales department, sending an e-mail to sales@mecolpress.com.
Courses can be requested both by Mecolpress customer and companies dealing with hot forging that have the necessity to examine in depth some themes.
Optimize the production with Mecolpress training courses
Mecolpress makes available to its customers a training service against payment whose aim is to provide useful information to the staff in charge of the presses in order to use the machines in the best performing way and to optimize the production.
Read this article to discover how training could help a customer of ours to reduce of 50% the maintenance interventions.
The problems of customer Alfa
Time ago a customer of ours, that we will name Alfa, contacted us because of his interest in custom-made training courses for forging machines proposed by Mecolpress. The reasons why he decided to activate the course were several.
First of all, the company employees were not adequately trained and could not use the forging machines in the best way. This implicated a frequent request of assistance from Mecolpress by the customer, and even if our intervention was very prompt, the company had to face up to the interruption of the productive process and to the additional costs connected to the customer care service.
In addition, the company hired new young but still not-expert personnel, however definitely open to technologic innovations and able to use the informatic devices of production machineries.
By their side there was also experienced personnel, working in the company for many years, with greater familiarity with forging techniques, but with some difficulties to approach their selves to the new digital techniques. Persuading them to change method was not so easy, because the long experience matured during years with their procedures.
In closing, the Alfa customer has at his disposal a various set of machines including dated presses, trimming presses, mechanical presses and a new hydraulic press, just bought.
For all these reasons, our customer has felt the need to take advantage of a new custom-made training course that can teach to the operators how to use the machines in the most performing way and to obtain the maximum output with minimum effort.
Mecolpress training course
According to the needs expressed by our customers we have planned a custom-made training course that takes account of forging machines in the company and of the type of forged parts.
The course is structured as follows:
- Introduction to hot forging;
- Explanation of drawings and simulation program in support of parts to be forged;
- Parts forging in the factory with an entirely devoted machine;
- Answers to questions of the personnel, detailed studies and explanations on problems regarding the production.
In particular, during the course very relevant matters were debated, such as die and process preliminary analysis, setting of specific parameters, driven setting of the hydraulic presses for parts with flash and without flash and analysis of output with simulations.
Result of the course
Our customer was particularly satisfied with our custom-made training course because of the obtained result.
Indeed, the personnel could acquire an increased competence regarding hot forging, both generally and specific, related to the company production type.
Moreover, the course has contributed to reinforce the team spirit among employees, that is of high importance to create a working environment based on collaboration. Indeed, activities of this kind contribute the personnel to interact more, to better work as a team and also to better face with the daily difficulties.
After our training our customer has decreased drastically the number of service requests against payment. Indeed, the operators in charge of machines can now use better the presses with a lesser wear and they can carry out in autonomy some activities of ordinary maintenance, without the need of Mecolpress technicians.

Hot forging of the brass: advantages of this material
The brass and its characteristics
The brass is an alloy composed of lead, copper, zinc and other metals, whose percentage can vary. The main component of this alloy is the copper that has a percentage between 55% and 62%. This high content of copper makes the brass a good electricity conductor and a material of easy mechanical machining because it does not wear out the cutting tools quickly as it instead happens for iron or steel.
Other typical features of the brass are:
- Recycling ease: brass is often remelt and reused to produce new parts.
- Resistance to a wide temperature range: during the hot forging process the brass is able to support, without creating particular critical issues, a moderate temperature range, this simplifies considerably the work, allowing a major tolerance in the usage of machineries.
- Lacking oxidation: During the heating phase inside the die, this metal is not subject to considerable oxidation.
- High corrosion resistance: the brass is a nonferrous alloy and therefore it does not get rusty.
Sectors of brass application
Thanks to its colour similiar to gold, the brass is used also for the realization of ornamental elements, home furnishing pieces such as for example handles and finishing for furniture, elements for clothing, including zippers and belt buckles.
Another sector of particular importance is composed by fluid control. This metal is particularly fitting for the production of valves, junction and fittings; since specific brass alloys with unimportant lead content were realized, the so produced pieces are therefore suitable to the contact with drinkable water. These special alloys are defined as Lead-free
In the end, as already underlined, the brass is a good electrical conductor and this characteristic makes him suitable for the realization of the electrical and electromechanical components, including switch parts, connections and terminals.
The hot forging process of the brass
The brass, that thanks to its particular plasticity permits to produce complicated geometrical shapes with simple processing, is hot forged as follows: when the press closes the dies with a single hit on the billet, it turns it into the part to be realized (in contrast to the steel that needs almost always a sequence of many hits). Inside the two halves of the die, that have the shape of the part to be realized, it is set down an enough quantity of metal in order to perfectly fulfill the entire cavity created by the two dies once they are overlapped and closed.
Presses for brass hot forging
For the hot forging of the brass it is possible to use continuous cycle presses or single cycle presses. The continuous cycle press is provided with a ram that moves continuously without stopping. The billets loading and the forged parts unloading is automatically adjusted by the electronic check. Instead, the single cycle press expects, at the dies reopening after a single hit, that the order for a new descent or closure of the dies must be sent by the user or by the PLC.
Mecolpress presses for the hot forging of the brass
For the hot forging of brass parts, Mecolpress proposes numerous mechanical and hydraulic presses with different characteristics according to the production typology that the customer wishes. Lately we have developed an innovative technology on our hydraulic presses for forging four parts with just a single hit that allows an important saving on the productive costs, come to discover how by reading the article!
Hot forging of the brass without flash, a success case
Brass hot forging and its application sectors
The hot forged brass pieces are used in many sectors, including, for example, clothing and constructions industry. The belt buckles, the zippers and door handles are all examples of parts produced with this material and obtained through hot forging presses.
Among the different application sectors, however, the one that sticks out mainly is the fluids control and hose fittings sector.
- Taps and fittings pieces,
- Valves for LPG tank and high-pressure gas,
- Ball valves for water, gas and oil,
- Watermeter bodies,
- Junctions for both the normal and floor heating, these are all brass pieces.
This type of product is currently affected on the market by a very strong competition of the Countries in which the manpower is cheaper and where probably in some cases a brass alloy is used that responds mainly to the local necessity and to the temporary availability, rather than to satisfy the international quality standard. To produce this kind of pieces in Europe, saving competitivity on the market represents therefore a challenge for many companies.
Hot forging without flash four brass parts at the same time
Speaking with a customer of ours who has the productive headquarter in Europe and who produces brass pieces, we could experience his real difficulty to remain on the market. From here comes the idea to find a solution that could allow him to increase the productivity and to reduce considerably the wasting material for sparing on the costs.
Our staff in collaboration with the technical office of the customer has identified then two different dies: one for the production of a hose junction connection and another for a curve of 90°. These new dies have been developed to take advantage of the potentiality of our hydraulic presses of ME serie of forging without flash and the result was to forge 4 parts at the same time.
In order to obtain this result, it is necessary to provide one of our standard hydraulic presses, such as the ME250/4G100, with some optional accessories (including also the billets loading system), that are conceptually simple but extremely well-performing.
This system is different due to its strongly innovative characteristic, since at the moment just the Mecolpress presses can provide this result (forging 4 pieces at the same time without flash) that surely brought great advantages also to our customer in terms of marginality on the product cost.
Through this specific press for the brass forging, it is possible to produce 4.500 parts at hour on average without flash.
This case study shows how it is possible to find solutions in the concrete and proactive collaboration with the customer that satisfy in the best way the specific productive necessities of that company and for its own specific interest.
Metals hot forging process
Metals forging: hot or cold forging?
The forging by means of presses of metals commonly used for the industrial production, such as aluminum and brass, can happen in two ways.
- The first one is the cold coining, carried out, for example, on a piece that already has its own shape and that is forged through the press in such a way to calibrate it and to compact it. The cold coining is suitable, above all, for small size parts and for great production batches, such as screws. The most suitable machines for this type of process are our screw presses.
- The metals hot forging is different from the cold one because it allows to obtain high quality pieces by means of an important deformation of the starting material. With the deformation of brass, copper, aluminum by means of hot forging presses it is possible, indeed, to produce particular shapes, having very complicated structures as well. In order to achieve this forging, Mecolpress proposes, beyond the already mentioned screw presses, also the mechanical and hydraulic presses according to the different production necessities expressed by the customer.
Mechanical and hydraulic presses for the hot forging
The mechanical press can hot forge even complicated pieces. At the end of the process, the forged parts can often have some remaining flash that can be eliminated by means of a trimming machine, machinery that is part of the products range that we offer. The eccentric mechanical press with continuous cycle is recommended for the customers who have high production necessities, while the hydraulic press is more advisable for parts having very complicated shapes and that would require, otherwise, the usage of a lot of material. This type of press permits, indeed, a saving of the input material, so offering to the forger a good margin on the product cost. Moreover, by forging the parts by means of hydraulic hot forging presses, at the end of the productive cycle the parts range that can be produced without flash is much wider, thanks to a progressive and programmable application of the forces. Another characteristic of this type of presses is the flexibility, given by the wide number of available functions.
Hot forging line
For the metals forging a furnace that can be electric (induction) or gas furnace and a press are needed. This is the base productive line for the aluminum, brass, titanium and steel processing; line that can be upstream completed with a sawing machine that cuts the metal bar in billets and with a graphitizing machine, where the billets are treated with the graphite before these are inserted in the furnace, so that these absorb better the heat and that are kept lubricated. The graphitizing, that offers remarkable advantages from a productive point of view, such as a minor gas consumption in the furnace and a superior durability of the dies, is just fitting for some specific production typologies. It is not recommended, for example, for the production of parts that once forged, must be chrome plated or exposed to further particular treatments. Our sales department is at the disposal of our customers for suggesting the best forging line composition according to the product and to application field.
Hot forged metals
The customer’s choice for a specific press for his own productive cycle is based on the material typology used by the forger and on the shapes to achieve.
For the brass forging the hydraulic press is more fitting than the screw press, that is better for the forging of titanium and steel. The eccentric mechanical presses are used for all the metals, even for the copper hot forging. Our sales department is at disposal of our customers for offering the best technical solution for every specific productive situation.
